Boat Tanks

Some spaces are all footprint and no height, and that is precisely where the Ronco Plastics B285 earns its keep: 6 gallons in a molding only 5.38" tall, spread across a 21.62" x 14.38" pan. Under a...

Every boat and van build has one system that gets designed last and crammed into whatever space is left. The B344 is the tank for that space: 7 gallons, 12 lb empty, explicitly listed by Ronco as...

The Ronco Plastics B395 is a 7 gallon B-series molding, the size you spec for a wash-down reservoir, a small galley supply, or a dinghy-scale fresh water system. It ships at 14 lb and disappears into...

The 3W is one of the oldest shapes in the Ronco book, and the reason is visible in the numbers: 12 gallons at 29.75 x 13.88 x 8.12 inches. That is a tank sized to the voids vehicles actually contain...

The Ronco Plastics B322 is the slimmest kind of useful: 5 gallons in a 21" x 8.25" x 8" bar that slots into the gap beside a wheel well, behind a console face, or under a cockpit side deck. Spaces...

The Ronco Plastics B390 holds 5 gallons in a 20 x 12 x 5.5 inch wafer, one of the thinnest moldings in the B-series. It exists for the jobs nothing else fits: under a step, behind a galley kick...

The Ronco Plastics B410 is a 5 gallon molding in an 18 x 13.5 x 7 inch low block, a different footprint from Ronco's other small tanks so that one of them fits whatever odd void your build presents...

Nine gallons is the honest small end of marine tankage, and the B442 makes it usable: a 19 x 15 x 9 inch molding that fits day boats, cuddy cabins, and camp trailers where the water system is a sink...

Nine gallons, 18.5 x 17 x 7.5 inches, 14 lb out of the box. The B532 is the tank you fit after everything else is installed - a shallow, almost-square molding that drops into the last usable void...

Eight gallons will not run a household, but on a boat it will run a galley - and the B121 exists for precisely that scale of honesty. It is one of the smallest marine water tanks Ronco molds: a 15 lb...

The Ronco Plastics B286 is the tank you buy when the space you have is a box: 15.38" x 13.5" x 13.5", 11 gallons, no wasted corners. It is a favorite for console boats and small campers because it...

Five inches. That is all the height the Ronco Plastics B288 asks for, spreading 9 gallons across a 32" x 15" pancake that slips beneath floors, berths and cockpit soles where nothing else goes...
